platform/x86: uniwill-laptop: Rename FN lock and super key lock attrs
It turns out that both sysfs attributes actually directly control
the FN lock status/super key enable status, rather than the
triggering of the associated events. This behavior was first observed
on a Tuxedo notebook and was belived to be a hardware quirk.
However, it seems that i simply misunderstood the manual of the
OEM software for Intel NUC devices. The correct behavior is:
- fn_lock_toggle_enable enables/disables FN lock mode
- super_key_toggle_enable enables/disables the super key
Rename both sysfs attributes to avoid confusing users.

f2fs-for-7.0-rc1
In this development cycle, we focused on several key performance optimizations:
1) introducing large folio support to enhance read speeds for immutable files,
2) reducing checkpoint=enable latency by flushing only committed dirty pages,
and 3) implementing tracepoints to diagnose and resolve lock priority inversion.
Additionally, we introduced the packed_ssa feature to optimize the SSA footprint
when utilizing large block sizes.
Enhancement:
- support large folio for immutable non-compressed case
- support non-4KB block size without packed_ssa feature
- optimize f2fs_enable_checkpoint() to avoid long delay
- optimize f2fs_overwrite_io() for f2fs_iomap_begin
- optimize NAT block loading during checkpoint write
- add write latency stats for NAT and SIT blocks in f2fs_write_checkpoint
- pin files do not require sbi->writepages lock for ordering
- avoid f2fs_map_blocks() for consecutive holes in readpages
- flush plug periodically during GC to maximize readahead effect
- add tracepoints to catch lock overheads
- add several sysfs entries to tune internal lock priorities
Bug fix:
- fix lock priority inversion issue
- fix incomplete block usage in compact SSA summaries
- fix to show simulate_lock_timeout correctly
- fix to avoid mapping wrong physical block for swapfile
- fix IS_CHECKPOINTED flag inconsistency issue caused by concurrent atomic
commit and checkpoint writes
- fix to avoid UAF in f2fs_write_end_io()

configfs-tsm-report: tdx_guest: Increase Quote buffer size to 128KB
Intel platforms are transitioning from traditional SGX-based attestation toward DICE-based attestation as part of a broader move toward open and standardized attestation models. DICE enables layered and extensible attestation, where evidence is accumulated across multiple boot stages. With SGX-based attestation, Quote sizes are typically under 8KB, as the payload consists primarily of Quote data and a small certificate bundle. Existing TDX guest code sizes the Quote buffer accordingly. DICE-based attestation produces significantly larger Quotes due to the inclusion of evidence (certificate chains) from multiple boot layers. The cumulative Quote size can reach approximately 100KB. Increase GET_QUOTE_BUF_SIZE to 128KB to ensure sufficient buffer capacity for DICE-based Quote payloads.

configfs-tsm-report: Document size limits for outblob attributes
The configfs-tsm-report interface can fail with -EFBIG when the attestation report generated by a TSM provider exceeds internal maximums (TSM_REPORT_OUTBLOB_MAX). However, this error condition and its handling are not currently documented in the ABI. Userspace tools need to understand how to interpret various error conditions when reading attestation reports. Document that reads fail with -EFBIG when reports exceed size limits, with guidance on how to resolve them.

Performance events changes for v7.0:
x86 PMU driver updates:
- Add support for the core PMU for Intel Diamond Rapids (DMR) CPUs.
Compared to previous iterations of the Intel PMU code, there's
been a lot of changes, which center around three main areas:
- Introduce the OFF-MODULE RESPONSE (OMR) facility to
replace the Off-Core Response (OCR) facility
- New PEBS data source encoding layout
- Support the new "RDPMC user disable" feature
(Dapeng Mi)
- Likewise, a large series adds uncore PMU support for
Intel Diamond Rapids (DMR) CPUs, which center around these
four main areas:
- DMR may have two Integrated I/O and Memory Hub (IMH) dies,
separate from the compute tile (CBB) dies. Each CBB and
each IMH die has its own discovery domain.
- Unlike prior CPUs that retrieve the global discovery table
portal exclusively via PCI or MSR, DMR uses PCI for IMH PMON
discovery and MSR for CBB PMON discovery.
- DMR introduces several new PMON types: SCA, HAMVF, D2D_ULA,
UBR, PCIE4, CRS, CPC, ITC, OTC, CMS, and PCIE6.
- IIO free-running counters in DMR are MMIO-based, unlike SPR.
(Zide Chen)
- Also add support for Add missing PMON units for Intel Panther Lake,
and support Nova Lake (NVL), which largely maps to Panther Lake.
(Zide Chen)
- KVM integration: Add support for mediated vPMUs (by Kan Liang
and Sean Christopherson, with fixes and cleanups by Peter Zijlstra,
Sandipan Das and Mingwei Zhang)
- Add Intel cstate driver to support for Wildcat Lake (WCL)
CPUs, which are a low-power variant of Panther Lake.
(Zide Chen)
- Add core, cstate and MSR PMU support for the Airmont NP Intel CPU
(aka MaxLinear Lightning Mountain), which maps to the existing
Airmont code. (Martin Schiller)
Performance enhancements:
- core: Speed up kexec shutdown by avoiding unnecessary
cross CPU calls. (Jan H. Schönherr)
- core: Fix slow perf_event_task_exit() with LBR callstacks
(Namhyung Kim)
User-space stack unwinding support:
- Various cleanups and refactorings in preparation to generalize
the unwinding code for other architectures. (Jens Remus)
Uprobes updates:
- Transition from kmap_atomic to kmap_local_page (Keke Ming)
- Fix incorrect lockdep condition in filter_chain() (Breno Leitao)
- Fix XOL allocation failure for 32-bit tasks (Oleg Nesterov)
Misc fixes and cleanups:
- s390: Remove kvm_types.h from Kbuild (Randy Dunlap)
- x86/intel/uncore: Convert comma to semicolon (Chen Ni)
- x86/uncore: Clean up const mismatch (Greg Kroah-Hartman)
- x86/ibs: Fix typo in dc_l2tlb_miss comment (Xiang-Bin Shi)

A slightly calmer cycle for docs this time around, though there is still a
fair amount going on, including:
- Some signs of life on the long-moribund Japanese translation
- Documentation on policies around the use of generative tools for patch
submissions, and a separate document intended for consumption by
generative tools.
- The completion of the move of the documentation tools to tools/docs. For
now we're leaving a /scripts/kernel-doc symlink behind to avoid breaking
scripts.
- Ongoing build-system work includes the incorporation of documentation in
Python code, better support for documenting variables, and lots of
improvements and fixes.
- Automatic linking of man-page references -- cat(1), for example -- to
the online pages in the HTML build.
...and the usual array of typo fixes and such.

"A slightly calmer cycle for docs this time around, though there is
still a fair amount going on, including:
- Some signs of life on the long-moribund Japanese translation
- Documentation on policies around the use of generative tools for
patch submissions, and a separate document intended for consumption
by generative tools
- The completion of the move of the documentation tools to
tools/docs. For now we're leaving a /scripts/kernel-doc symlink
behind to avoid breaking scripts
- Ongoing build-system work includes the incorporation of
documentation in Python code, better support for documenting

Pull block updates from Jens Axboe:
- Support for batch request processing for ublk, improving the
efficiency of the kernel/ublk server communication. This can yield
nice 7-12% performance improvements
- Support for integrity data for ublk
- Various other ublk improvements and additions, including a ton of
selftests additions and updated
- Move the handling of blk-crypto software fallback from below the
block layer to above it. This reduces the complexity of dealing with
bio splitting
- Series fixing a number of potential deadlocks in blk-mq related to
the queue usage counter and writeback throttling and rq-qos debugfs
handling
- Add an async_depth queue attribute, to resolve a performance
regression that's been around for a qhilw related to the scheduler
depth handling
- Only use task_work for IOPOLL completions on NVMe, if it is necessary
to do so. An earlier fix for an issue resulted in all these
completions being punted to task_work, to guarantee that completions
were only run for a given io_uring ring when it was local to that
ring. With the new changes, we can detect if it's necessary to use
task_work or not, and avoid it if possible.

- Fix refcount underflow in device unmap path
- Handle PREFLUSH and NOUNMAP flags properly in protocol

Pull erofs updates from Gao Xiang:
"In this cycle, inode page cache sharing among filesystems on the same
machine is now supported, which is particularly useful for
high-density hosts running tens of thousands of containers.
In addition, we fully isolate the EROFS core on-disk format from other
optional encoded layouts since the core on-disk part is designed to be
simple, effective, and secure. Users can use the core format to build
unique golden immutable images and import their filesystem trees
directly from raw block devices via DMA, page-mapped DAX devices,
and/or file-backed mounts without having to worry about unnecessary
intrinsic consistency issues found in other generic filesystems by
design. However, the full vision is still working in progress and will
spend more time to achieve final goals.
There are other improvements and bug fixes as usual, as listed below:
- Support inode page cache sharing among filesystems
- Formally separate optional encoded (aka compressed) inode layouts
(and the implementations) from the EROFS core on-disk aligned plain

erofs: separate plain and compressed filesystems formally
The EROFS on-disk format uses a tiny, plain metadata design that prioritizes performance and minimizes complex inconsistencies against common writable disk filesystems (almost all serious metadata inconsistency cannot happen in well-designed immutable filesystems like EROFS). EROFS deliberately avoids artificial design flaws to eliminate serious security risks from untrusted remote sources by design, although human-made implementation bugs can still happen sometimes. Currently, there is no strict check to prevent compressed inodes, especially LZ4-compressed inodes, from being read in plain filesystems. Starting with erofs-utils 1.0 and Linux 5.3, LZ4_0PADDING sb feature is automatically enabled for LZ4-compressed EROFS images to support in-place decompression. Furthermore, since Linux 5.4 LTS is no longer supported, we no longer need to handle ancient LZ4-compressed EROFS images generated by erofs-utils prior to 1.0. To formally distinguish different filesystem types for improved security: - Use the presence of LZ4_0PADDING or a non-zero `dsb->u1.lz4_max_distance` as a marker for compressed filesystems containing LZ4-compressed inodes only; - For other algorithms, use `dsb->u1.available_compr_algs` bitmap. Note: LZ4_0PADDING has been supported since Linux 5.4 (the first formal kernel version), so exposing it via sysfs is no longer necessary and is now deprecated (but remain it for five more years until 2031): `dsb->u1` has been strictly non-zero for all EROFS images containing compressed inodes starting with erofs-utils v1.3 and it is actually a much better marker for compressed filesystems.

IIO: New device support, features and cleanup for the 6.20/7.0 cycle.
Slightly messier than normal unfortunately due to some conflicts and build config bugs related to I3C drivers. One last minute Kconfig fix right at the top after a linux-next report. I've simplified the Kconfig and made it match other instances in the kernel so that should be safe enough despite short soak time in front of build bots. Merge of an immutable branch from I3C to get some stubs that were missing and caused build issues with dual I2C / I3C drivers. This also brought in a drop of some deprecated interfaces so there is also one patch to update a new driver to not use those. We are having another go at using cleanup.h magic with the IIO mode claim functions after backing out last try at this. This time we have wrappers around the new ACQUIRE() and ACQUIRE_ERR() macros. Having been burnt once, we will be taking it a bit more slowly this time wrt to wide adoption of these! Thanks in particular to Kurt for taking on this core IIO work. New Device Support ================== adi,ad18113 - New driver to support the AD18113 amplifier - an interesting device due to the external bypass paths where we need to describe what gain those paths have in DT. Longer term it will be interesting to see if this simplistic description is enough for real deployments. adi,ad4062 - New driver for the AD4060 and AD4052 SAR ADCs including trigger, event and GPIO controller support. Follow up patch replaced use of some deprecated I3C interfaces prior to the I3C immutable branch merge as that includes dropping them. adi,ad4134 - New driver for the AD4134 24bit 4 channel simultaneous sampling ADC. adi,ad7768-1, - Add support for the ADAQ767-1, ADAQ7768-1 and ADAQ7769-1 ADCs after some rework to enable the driver to support multiple device types. adi,ad9467 - Add support for the similar ad9211 ADC to this existing driver. - Make the selection of 2s comp mode explicit for normal operation and switch to offset binary when entering calibration mode. honeywell,abp2 - New driver to support this huge family (100+) of board mount pressure and temperature sensors. maxim,max22007 - New drier for this 4 channel DAC. memsic,mmc5633 - New driver for this I2C/I3C magnetometer. Follow on patches fixed up issues related to single driver supporting both bus types. microchip,mcp747feb02 - New driver for the Microchip MCP47F(E/V)B(0/1/2)1, MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8 buffered voltage output DACs. nxp,sar-adc - New driver support ADCs found on s32g2 and s32g3 platforms. ti,ads1018 - New drier for the ADS1018 and ADS1118 SPI ADCs. ti,ads131m02 - New driver supporting ADS131M(02/03/04/06/08)24-bit simultaneous sampling ADCs. Features ======== iio-core - New IIO_DEV_ACQUIRE_DIRECT_MODE() / IIO_DEV_ACQUIRE_FAILED() + equivalents for the much rarer case where the mode needs pinning whether or not it is in direct mode. These use the ACQUIRE() / ACQUIRE_ERR() infrastructure underneath to provide both simple checks on whether we got the requested mode and to provide scope based release. Applied in a few initial drivers. adi,ad9467 - Support calibbias control adi,adf4377 - Add support to act as a clock provider. adi,adxl380 - Support low power 1KHz sampling frequency mode.

Slightly messier than normal unfortunately due to some conflicts and build config bugs related to I3C drivers. One last minute Kconfig fix right at the top after a linux-next report. I've simplified the Kconfig and made it match other instances in the kernel so that should be safe enough despite short soak time in front of build bots. Merge of an immutable branch from I3C to get some stubs that were missing and caused build issues with dual I2C / I3C drivers. This also brought in a drop of some deprecated interfaces so there is also one patch to update a new driver to not use those. We are having another go at using cleanup.h magic with the IIO mode claim functions after backing out last try at this. This time we have wrappers around the new ACQUIRE() and ACQUIRE_ERR() macros. Having been burnt once, we will be taking it a bit more slowly this time wrt to wide adoption of these! Thanks in particular to Kurt for taking on this core IIO work. New Device Support ================== adi,ad18113 - New driver to support the AD18113 amplifier - an interesting device due to the external bypass paths where we need to describe what gain those paths have in DT. Longer term it will be interesting to see if this simplistic description is enough for real deployments. adi,ad4062 - New driver for the AD4060 and AD4052 SAR ADCs including trigger, event and GPIO controller support. Follow up patch replaced use of some deprecated I3C interfaces prior to the I3C immutable branch merge as that includes dropping them. adi,ad4134 - New driver for the AD4134 24bit 4 channel simultaneous sampling ADC. adi,ad7768-1, - Add support for the ADAQ767-1, ADAQ7768-1 and ADAQ7769-1 ADCs after some rework to enable the driver to support multiple device types. adi,ad9467 - Add support for the similar ad9211 ADC to this existing driver. - Make the selection of 2s comp mode explicit for normal operation and switch to offset binary when entering calibration mode. honeywell,abp2 - New driver to support this huge family (100+) of board mount pressure and temperature sensors. maxim,max22007 - New drier for this 4 channel DAC. memsic,mmc5633 - New driver for this I2C/I3C magnetometer. Follow on patches fixed up issues related to single driver supporting both bus types. microchip,mcp747feb02 - New driver for the Microchip MCP47F(E/V)B(0/1/2)1, MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8 buffered voltage output DACs. nxp,sar-adc - New driver support ADCs found on s32g2 and s32g3 platforms. ti,ads1018 - New drier for the ADS1018 and ADS1118 SPI ADCs. ti,ads131m02 - New driver supporting ADS131M(02/03/04/06/08)24-bit simultaneous sampling ADCs. Features ======== iio-core - New IIO_DEV_ACQUIRE_DIRECT_MODE() / IIO_DEV_ACQUIRE_FAILED() + equivalents for the much rarer case where the mode needs pinning whether or not it is in direct mode. These use the ACQUIRE() / ACQUIRE_ERR() infrastructure underneath to provide both simple checks on whether we got the requested mode and to provide scope based release. Applied in a few initial drivers. adi,ad9467 - Support calibbias control adi,adf4377 - Add support to act as a clock provider. adi,adxl380 - Support low power 1KHz sampling frequency mode.

f2fs: fix lock priority inversion issue
If userspace thread has held f2fs rw semaphore, due to its low priority, it could be runnable or preempted state for long time, during the time, it will block high priority thread which is trying to grab the same rw semaphore, e.g. cp_rwsem, io_rwsem... To fix such issue, let's detect thread's priority when it tries to grab f2fs_rwsem lock, if the priority is lower than a priority threshold, let's uplift the priority before it enters into critical region of lock, and restore the priority after it leaves from critical region. Meanwhile, introducing two new sysfs nodes: - /sys/fs/f2fs/<disk>/adjust_lock_priority, it is used to control whether the functionality is enable or not. ========== ================== Flag_Value Flag_Description ========== ================== 0x00000000 Disabled (default) 0x00000001 cp_rwsem 0x00000002 node_change 0x00000004 node_write 0x00000008 gc_lock 0x00000010 cp_global 0x00000020 io_rwsem ========== ================== - /sys/fs/f2fs/<disk>/lock_duration_priority, it is used to control priority threshold.

iio: cros_ec: Allow enabling/disabling calibration mode
'calibrate' was a one-shot event sent to the sensor to calibrate itself. It is used on Bosch sensors (BMI160, BMA254). Light sensors work differently: They are first put in calibration mode, tests are run to collect information and calculate the calibration values to apply. Once done, the sensors are put back in normal mode. Accept boolean true and false (not just true) to enter/exit calibration state. Check "echo 0 > calibrate" is supported.

This new attribute allows user-space to configure the numeric priority of alternate modes managing their preferred order of operation. If a new priority value conflicts with an existing mode's priority, the priorities of the conflicting mode and all subsequent modes are automatically incremented to ensure uniqueness.

Revert "PCI/TSM: Report active IDE streams"
The proposed ABI failed to account for multiple host bridges with the same stream name. The fix needs to namespace streams or otherwise link back to the host bridge, but a change like that is too big for a fix. Given this ABI never saw a released kernel, delete it for now and bring it back later with this issue addressed.

erofs: tidy up synchronous decompression
- Get rid of `sbi->opt.max_sync_decompress_pages` since it's fixed as 3 all the time; - Add Z_EROFS_MAX_SYNC_DECOMPRESS_BYTES in bytes instead of in pages, since for non-4K pages, 3-page limitation makes no sense; - Move `sync_decompress` to sbi to avoid unexpected remount impact; - Fold z_erofs_is_sync_decompress() into its caller; - Better description of sysfs entry `sync_decompress`.

perf/x86/intel: Add support for rdpmc user disable feature
Starting with Panther Cove, the rdpmc user disable feature is supported. This feature allows the perf system to disable user space rdpmc reads at the counter level. Currently, when a global counter is active, any user with rdpmc rights can read it, even if perf access permissions forbid it (e.g., disallow reading ring 0 counters). The rdpmc user disable feature mitigates this security concern. Details: - A new RDPMC_USR_DISABLE bit (bit 37) in each EVNTSELx MSR indicates that the GP counter cannot be read by RDPMC in ring 3. - New RDPMC_USR_DISABLE bits in IA32_FIXED_CTR_CTRL MSR (bits 33, 37, 41, 45, etc.) for fixed counters 0, 1, 2, 3, etc. - When calling rdpmc instruction for counter x, the following pseudo code demonstrates how the counter value is obtained: If (!CPL0 && RDPMC_USR_DISABLE[x] == 1) ? 0 : counter_value; - RDPMC_USR_DISABLE is enumerated by CPUID.0x23.0.EBX[2]. This patch extends the current global user space rdpmc control logic via the sysfs interface (/sys/devices/cpu/rdpmc) as follows: - rdpmc = 0: Global user space rdpmc and counter-level user space rdpmc for all counters are both disabled. - rdpmc = 1: Global user space rdpmc is enabled during the mmap-enabled time window, and counter-level user space rdpmc is enabled only for non-system-wide events. This prevents counter data leaks as count data is cleared during context switches. - rdpmc = 2: Global user space rdpmc and counter-level user space rdpmc for all counters are enabled unconditionally. The new rdpmc settings only affect newly activated perf events; currently active perf events remain unaffected. This simplifies and cleans up the code. The default value of rdpmc remains unchanged at 1. For more details about rdpmc user disable, please refer to chapter 15 "RDPMC USER DISABLE" in ISE documentation.
